PAN-EX: a pooled analysis of two trials of neoadjuvant chemotherapy followed by chemoradiotherapy in MRI-defined, locally advanced rectal cancer
2016
This analysis confirms that administering neoadjuvant chemotherapy (NACT) before chemoradiotherapy (CRT) could be a potential option for high-risk, locally advanced rectal cancer. In this setting, MRI tumour regression grade is an independent prognostic factor and, when assessed after NACT, may predict the probability and magnitude of incremental benefit from sequential CRT.EXPERT and EXPERT-C were phase II clinical trials of neoadjuvant chemotherapy (NACT) followed by chemoradiotherapy (CRT) in high-risk, locally advanced rectal cancer (LARC). We pooled individual patient data from these trials. The primary objective was overall survival (OS) in the intention-to-treat (ITT) population. Pro…
Direction-dependent activation of the insular cortex during vertical and horizontal hand movements
2016
International audience; The planning of any motor action requires a complex multisensory processing by the brain. Gravity - immutable on Earth - has been shown to be a key input to these mechanisms. Seminal fMRI studies performed during visual perception of falling objects and self-motion demonstrated that humans represent the action of gravity in parts of the cortical vestibular system; in particular, the insular cortex and the cerebellum. However, little is known as to whether a specific neural network is engaged when processing non-visual signals relevant to gravity. We asked participants to perform vertical and horizontal hand movements without visual control, while lying in a 3T-MRI sc…
Topical azithromycin for the prevention of Lyme borreliosis: a randomised, placebo-controlled, phase 3 efficacy trial
2017
Summary Background Lyme borreliosis develops in 1–5% of individuals bitten by ticks, but with a diagnostic gap affecting up to 30% of patients, a broadly applicable pharmacological prevention strategy is needed. Topical azithromycin effectively eradicated Borrelia burgdorferi sensu lato from the skin in preclinical studies. We assessed its efficacy in human beings. Methods In this randomised, double-blind, placebo-controlled, multicentre trial done in 28 study sites in Germany and Austria, adults were equally assigned to receive topical 10% azithromycin or placebo twice daily for 3 consecutive days, within 72 h of a tick bite being confirmed. Randomisation numbers, which were stratified by …
Chromosome 15q BP3 to BP5 deletion is a likely locus for speech delay and language impairment: Report on a four‐member family and an unrelated boy
2020
Abstract Background Deletions in chromosome 15q13 have been reported both in healthy people and individuals with a wide range of behavioral and neuropsychiatric disturbances. Six main breakpoint (BP) subregions (BP1‐BP6) are mapped to the 15q13 region and three further embedded BP regions (BP3‐BP5). The deletion at BP4‐BP5 is the rearrangement most frequently observed compared to other known deletions in BP3‐BP5 and BP3‐BP4 regions. Deletions of each of these three regions have previously been implicated in a variable range of clinical phenotypes, including minor dysmorphism, developmental delay/intellectual disability, epilepsy, autism spectrum disorders, behavioral disturbances, and speec…
Optimal Cut Points for Remission and Response for the German Version of the Social Phobia Anxiety Inventory (SPAI).
2018
The German version of the Social Phobia and Anxiety Inventory (SPAI-G) is a validated measure for the detection of social anxiety disorder (SAD). The aim of the present study was to develop optimal cut points (OC) for remission and response to treatment for the SPAI-G.We used Receiver Operating Characteristic methods and bootstrapping to analyse the data of 359 patients after psychotherapeutic treatment. OCs where defined as the cut points with the highest sensitivity and specificity after bootstrapping.For remission, an OC of 2.79 was found, and for response, a change in score from pre- to posttreatment by 11% yielded best results.The OC we identified for remissionmay be used to improve th…
Patients Who Miss Initial Appointments in Community Psychiatry? a Spanish Community Analysis
1999
Objectives : To identify factors that predict which patients, when referred by their GP, make a first appointment at a Mental Health Centre and then fail to attend. Method: Sequential observational study in which data was collected for one year on all the people (1311) with an arranged date for an initial appointment at an urban Community Mental Health Centre. Results: Approximately 25% of patients who request an initial appointment fail to attend. The variables that predict non-attendance are: the lack of a telephone number for contact, the time lapse before the appointment, and when drug-addiction is the reason for requesting the appointment. One variable that results in a specific kind o…
Mutation spectrum and clinical investigation of achromatopsia patients with mutations in the GNAT2 gene
2019
Achromatopsia (ACHM) is a hereditary cone photoreceptor disorder characterized by the inability to discriminate colors, nystagmus, photophobia, and low-visual acuity. Six genes have been associated with this rare autosomal recessively inherited disease, including the GNAT2 gene encoding the catalytic α-subunit of the G-protein transducin which is expressed in the cone photoreceptor outer segment. Out of a cohort of 1,116 independent families diagnosed with a primary clinical diagnosis of ACHM, we identified 23 patients with ACHM from 19 independent families with likely causative mutations in GNAT2, representing 1.7% of our large ACHM cohort. In total 22 different potentially disease-causing…
Single-Nucleotide Polymorphism Array-Based Karyotyping of Acute Promyelocytic Leukemia
2014
Acute promyelocytic leukemia (APL) is characterized by the t(15;17)(q22;q21), but additional chromosomal abnormalities (ACA) and other rearrangements can contribute in the development of the whole leukemic phenotype. We hypothesized that some ACA not detected by conventional techniques may be informative of the onset of APL. We performed the high-resolution SNP array (SNP-A) 6.0 (Affymetrix) in 48 patients diagnosed with APL on matched diagnosis and remission sample. Forty-six abnormalities were found as an acquired event in 23 patients (48%): 22 duplications, 23 deletions and 1 Copy-Neutral Loss of Heterozygocity (CN-LOH), being a duplication of 8(q24) (23%) and a deletion of 7(q33-qter) (…
Characterization of 14 novel deletions underlying Rubinstein–Taybi syndrome: an update of the CREBBP deletion repertoire
2015
Rubinstein–Taybi syndrome (RSTS) is a rare, clinically heterogeneous disorder characterized by cognitive impairment and several multiple congenital anomalies. The syndrome is caused by almost private point mutations in the CREBBP (~55 % of cases) and EP300 (~8 %) genes. The CREBBP mutational spectrum is variegated and characterized by point mutations (30–50 %) and deletions (~10 %). The latter are diverse in size and genomic position and remove either the whole CREBBP gene and its flanking regions or only an intragenic portion. Here, we report 14 novel CREBBP deletions ranging from single exons to the whole gene and flanking regions which were identified by applying complementary cytomolecu…
Mutation analyses in 17 patients with deficiency in acid β-galactosidase: three novel point mutations and high correlation of mutation W273L with Mor…
2001
An inherited deficiency in beta-galactosidase can result in GM1 gangliosidosis, with several phenotypes of generalized or chronic psychomotor deterioration, as well as in Morquio disease type B, a characteristic mucopolysaccharidosis free of neurological symptoms. We performed mutation analyses in 17 juvenile and adult patients from various European regions with a deficiency in beta-galactosidase and skeletal abnormalities. Fifteen of these had the Morquio B phenotype and have remained neurologically healthy until now while the two others exhibited psychomotor retardation of juvenile onset. A two-base substitution (851-852TG--CT; W273L) was present in 14 of the 15 Morquio B cases. Even if o…
